Photoshop :: How To Turn Black Or Dark Coloured Clothing / Items White

I have been using Photoshop for a while now but have recently been invited to design some sportswear. I want to initially take existing clothing and change the colours and add designs. As an example, how would I get this soccer kit to be either all white or white on everything apart from the shorts?

I have managed to get yellow to go white using the hue/saturation tool but dark colours seem like its impossible. I do also want to know how to go from white to a darker colour but maybe I should save that for my next thread.
